03.01.16E Decomposition Into Policy-Relevant Subcomponents

Statement

Decompose CUI into {{ insert: param, A.03.01.16E.ODP.01 }} for submission to policy enforcement mechanisms when transferring CUI between different security domains.

Guidance

Decomposing CUI into policy-relevant subcomponents prior to information transfer facilitates policy decisions on source, destination, certificates, and other security-related component differentiators. Policy enforcement mechanisms apply filtering, inspection, and/or sanitization rules to the policy-relevant subcomponents of information to facilitate flow enforcement prior to transferring such information to different security domains. This requirement enhances SP 800-171 requirement 03.01.03.

Statement

• (includes preempt) Ensure that the threat event does not have an impact.

  • Reduce likelihood of occurrence and/or reduce likelihood of impact.

  • The adversary’s efforts or resources cannot be applied or are wasted.

• (includes exert) Make it more difficult for threat events to cause adverse impacts or consequences.

  • Reduce likelihood of impact and reduce level of impact.

  • Adversary activities are restricted in scope, fail to achieve full effect, do not take place in accordance with adversary timeline, or require greater resources than adversary had planned.

Assessment objective

when transferring information between different security domains, CUI is decomposed into {{ insert: param, A.03.01.16E.ODP.01 }} for submission to policy enforcement mechanisms

Assessment method

• Access control policy information flow control policies procedures addressing information flow enforcement system design documentation system configuration settings and associated documentation system audit records system security plan other relevant documents or records

Assessment method

• System/network administrators personnel with information security responsibilities system developers

Assessment method

• Mechanisms implementing information flow enforcement policy
